SHOVEL-BLADE.

Specification of Letters Patent.

Patented Marc 1909.

Application filed September 22, 1908. Serial No; 454,173.

To all whom it may concern:

Be it known that I,'HARLEY K. W001), citizen of the United States, residing at Pique, in the countv of Miami and State of (H110, have invented certain new and useful Improvements in, Shovel-Blades, of which,

the following isa specification.

This invention comprehends certain new and useful improvements in shovels, spades, scoops and similar tools, and theinvention has for its object an improved construction.

of tool of this character embodying a blade provided with a. longitudinal corrugation extending the blade nearly to the fro ducing a long'itu rearwardly toward and preferably the saidzcorrugation proinaldepression in one face acorrespondingly rounded I'll) on the other faceof the blade, said corrugation serving to strengthen the tool, to enable the tool to enter the material more easily, and to reduce the friction on the portion thereof; Fi

blade. of the tool and the consequent wear which friction produces." For-a full understanding of the invention,

reference is to be had to the following description and accompanying drawings, in

which:

Figure 1 is a side elevation of a shovel constructed in accordance with m invention. Fig. 2 is a to plan view of the blade end of the shovel; 4 is a transverse sectional view on the line 44 of Fig. 1 Fig. 5 is a similar view on the line 5-5 of F i 1, and Fig. 6 is a transverse sectional view illustrating'a modified form of corrugation.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring tothe drawing, thenumeral l designates the blade of a scoop or'shovel, said blade being rounded in the present instance and being constructedof a single piece of sheet metal provided with the integral tangs 2 for the reception of the handle 3. The blade 1 is formed with a frog 4 and with a corrugation 5, said corrugation extending from a oint 6 of the blade rearwardly in. a

longituc al direction and terminating at its from the point or front edge of g. 3 is a bottom planview of a from the frog forwardly in the upper face of the blade and a rounding rib on the lower face of the blade, the rear end of the rihterminating in the point or toe of the frog.

From the foregoing description in connection with the accompanying drawing, it is manifest that by producing theblade with the corrugation 5, as above described, not only is the blade strengthened, but friction thereon is'reduced and the consequent wear avoided, while at the same time the rib formed b 'the corrugation renders the device capable of being more easily entered in the material.

The invention is shown in the accompanying drawings as embodied in a scoop of the type that is known as a breaking down scoop, used in unloading coal, but it is to be understood that my invention is not limited in this regard, but is applicable equally on all forms I and types of scoops, shovels, spades and similar tools.

It is to be understood that the invention is not limited to having the rounded rib on the lower face 'of the blade and the depression on the upper face of the blade. For instance,

as illustrated in Fig. 6, 1 a designates ,a shovel blade in which the corrugation 5 produces the rib on the up er face of the blade and a depression in the ower face.

Having thus described the invention, what is claimed as newis:

1. As a new article of manufacture, a blade I for shovels. or the like provided with a frog and a longitudinal corrugation extending and terminating in the f-ront edge of blade.

2. Asa new article of manufacture, a blade for shovels or the. provided at its rear end with a frog which forms a depression in the lower face of the blade and a protuberant-r in the upper face of the blade and a longitudinal corrugation which extends forwardly from said frog, and which terminates in the front edge of the blade, said corrugation forming a depression in the upper face of the blade, and a'rounded rib projecting below the lower face thereof. r

. 1 In testimony whereof I aflix'my signature in presence of. two witnesses.
